Regex Genie
Describe it in plain language, get the regex explained and tested
Description
Turn a plain-language description into a ready-to-use regular expression. The description you type leaves the browser: it goes to the federicocalo.dev backend, which forwards it to the AI provider currently in use (OpenRouter, free tier); the AI generates the pattern, explains it step by step and shows test cases (input → match yes/no). The provider is asked not to use prompts for training; data can be processed outside the European Union, so do not enter personal or confidential data. The pattern check against the browser regex engine and the local cache of generated regexes stay in the browser. No telemetry.
